Essay

A construction engineer has designed an experiment to investigate 3 different types of pressure treatment that can be applied to raw lumber. The experiment was conducted as a completely randomized design in which 30 pieces of raw lumber were selected with 10 assigned at random to each of the three pressure treatments. The response variable was water repellency. The sample means and the sum of squared error are given below.
